Effectiveness of forest density reduction treatments for increasing drought resistance of ponderosa pine growth.

As the climate changes, it is increasingly important to understand how forests will respond to drought and how forest management can influence those outcomes. In many forests that have become unnaturally dense, "restoration treatments," which decrease stand density using fire and/or mechanical thinning, are generally associated with reduced mortality during drought. However, the effects of such treatments on tree growth during drought are less clear.

Continental-scale tree-ring-based projection of Douglas-fir growth: Testing the limits of space-for-time substitution.

A central challenge in global change research is the projection of the future behavior of a system based upon past observations. Tree-ring data have been used increasingly over the last decade to project tree growth and forest ecosystem vulnerability under future climate conditions. But how can the response of tree growth to past climate variation predict the future, when the future does not look like the past? Space-for-time substitution (SFTS) is one way to overcome the problem of extrapolation: the response at a given location in a warmer future is assumed to follow the response at a warmer location today.

Biochar and nitrogen application rates effect on phosphorus removal from a mixed grass sward irrigated with reclaimed wastewater.

This 2-year (2017 and 2018) field study evaluated biochar and nitrogen application rates effect on herbage phosphorus (P) and nitrogen (N) removal from a mixed-grass sward of tall fescue [Schedonorus arundinaceus (Schreb.) Dumort] and Kentucky bluegrass (Poa pratensis L.) irrigated with treated wastewater.

Uptake of permanent contraception among women in sub-Saharan Africa: a literature review of barriers and facilitators.

Objective: Uptake of permanent contraception among women remains low in sub-Saharan Africa compared to other regions. We aimed to synthesize available evidence on barriers to, and facilitators of permanent contraception with regards to tubal ligation among women in sub-Saharan Africa.

Study Design: We reviewed literature on tubal ligation among African women published between January 1, 2000 and October 30, 2017.

Restoring dryland old fields with native shrubs and grasses: Does facilitation and seed source matter?

Restoration of agricultural fields is challenging, especially in arid and semi-arid ecosystems. We conducted experiments in two fields in the Great Basin, USA, which differed in cultivation history and fertility. We tested the effects of different levels of functional diversity (planting grasses and shrubs together, vs.

Interrater Reliability of a Field-Based Preschool Movement Skills Assessment.

Objective: To determine the interrater reliability of the Preschool Movement Assessment (PMA), a unique field-based assessment tool for use by early childhood professionals in preschool settings.

Methods: A total of 123 preschool children, aged 3-5years, were assessed by 6 trained raters using the PMA tool in an intervention. Interrater agreement on individual items of the PMA was determined using the kappa (κ) and intraclass correlation coefficient statistics.

About feeding children: factor structure and internal reliability of a survey to assess mealtime strategies and beliefs of early childhood education teachers.

Background: Children spend a substantial amount of time in early care and education (ECE) settings and may eat a majority of their diet in this setting. While there are several instruments focused on measuring factors of the ECE environment that may influence diet and weight outcomes, there are few comprehensive, valid, and reliable measures for collecting self-report of ECE providers' feeding practices. The purpose of this study was to establish the factor structure and internal reliability of a survey developed to measure practices and beliefs of ECE providers relative to feeding children.

The Use of Social Media and mEMA Technology in Comparing Compliance Rate Among Users.

Compliance can be defined as the extent to which a person's behavior corresponds with agreed recommendations. Within the context of lifestyle intervention, this may refer to physical activity, diet modifications, or lifestyle intervention program attendance or attrition. For lifestyle intervention programs to be successful (as measured against a variety of health and lifestyle markers), it is crucial for individuals to comply as best they can to the recommendations or instructions provided by the researchers.

Dynamic Energy Balance: An Integrated Framework for Discussing Diet and Physical Activity in Obesity Prevention-Is it More than Eating Less and Exercising More?

Understanding the dynamic nature of energy balance, and the interrelated and synergistic roles of diet and physical activity (PA) on body weight, will enable nutrition educators to be more effective in implementing obesity prevention education. Although most educators recognize that diet and PA are important for weight management, they may not fully understand their impact on energy flux and how diet alters energy expenditure and energy expenditure alters diet. Many nutrition educators have little training in exercise science; thus, they may not have the knowledge essential to understanding the benefits of PA for health or weight management beyond burning calories.

Potential Use of Food/Activity, Parenting Style, and Caregiver Feeding Style Measurement Tools with American Indian Families: A Brief Report.

Objective To provide preliminary descriptive data on caregiver and child weight status, parenting styles, feeding styles, and feeding practices of a small American Indian sample. Methods Participants included a subsample of American Indian caregivers (n = 23) identified from a larger study that was conducted in five states. Using previously validated instruments, means, standard deviations, and ranges for general parenting styles, feeding styles, and feeding practices were explored.

Family Resiliency: A Neglected Perspective in Addressing Obesity in Young Children.

Background: Traditional research primarily details child obesity from a risk perspective. Risk factors are disproportionately higher in children raised in poverty, thus negatively influencing the weight status of low-income children. Borrowing from the field of family studies, the concept of family resiliency might provide a unique perspective for discussions regarding childhood obesity, by helping to identify mediating or moderating protective mechanisms that are present within the family context.

Breastfeeding Knowledge and Attitudes of Nevada Health Care Professionals Remain Virtually Unchanged over 10 Years.

Background: It is prudent that health care professionals remain cognizant of breastfeeding-related issues to support nursing mothers. In 1995, Freed and colleagues noted deficits in breastfeeding knowledge among family medicine, pediatric, and obstetrics/gynecology residents and practitioners. Others reported similar findings despite calls to action and reports of successful breastfeeding interventions.

A gender-specific approach to improving substance abuse treatment for women: The Healthy Steps to Freedom program.

Given that women increasingly report using drugs to lose weight, substance abuse treatment programs must include body image, weight, eating pathology, and health knowledge as core intervention targets. This study tested the efficacy of a supplemental health and body image curriculum designed for women in substance abuse treatment who report weight concerns called Healthy Steps to Freedom (HSF). Data from 124 adult women recruited from substance abuse treatment facilities in southern Nevada completed measures of drug use, body dissatisfaction, eating pathology, thin-ideal internalization, and health knowledge/behaviors before and after participation in the 12-week HSF program.

Child care provider training and a supportive feeding environment in child care settings in 4 states, 2003.

Introduction: Strategies to prevent adult chronic diseases, including obesity, must start in childhood. Because many preschool-aged children spend mealtimes in child care facilities, staff should be taught supportive feeding practices for childhood obesity prevention. Higher obesity rates among low-income children suggest that centers providing care to these children require special attention.

Challenges of collaboration to address health disparities in the rapidly growing community of Las Vegas, Nevada.

Collaboration was established between a university and the faith-based community in Clark County, Nevada to develop a coalition to address chronic disease in the African American population. The university faculty enlisted several churches and health related agencies to join the coalition. The challenges of collaborating with a community coalition to develop and implement a grant are discussed.

About feeding children: mealtimes in child-care centers in four western states.

This study was conducted to describe mealtimes and explore routines, policies, and training in child-care centers. Following an intensive review of mealtimes, staff and director questionnaires were created. Using a stratified random sampling protocol and following the Tailored Design Method, directors and staff from licensed child-care centers from California, Colorado, Idaho, and Nevada were surveyed.

Evaluation of a community-based health promotion program for the elderly: lessons from Seniors CAN.

Purpose: To evaluate the effects of a community-based educational program designed to promote health by enhancing older adults' mastery while decreasing loneliness and stress.

Methods: Between 1999 and 2004, 339 older adults who participated in Seniors CAN completed standardized assessments of mastery, loneliness, and stress, prior to and upon completion of the 4-month intervention. Participants'scores were compared using paired t-tests to measure changes from preintervention to postintervention.

Implementing the American Diabetes Association's nutrition recommendations.

Evidence-based "Nutrition Principles and Recommendations for the Treatment and Prevention of Diabetes and Related Complications" outline the goals of medical nutrition therapy for type 1 and type 2 diabetes mellitus. Those goals are (1) to attain and maintain optimal metabolic outcomes, (2) to prevent and treat the chronic complications of diabetes, (3) to improve health through healthy food choices and through physical activity, and (4) to address individual patient nutritional needs. Discussion focuses on moderate caloric restriction and an increase in physical activity.
